v VALVE.

To all whom it may concern: y' Be it known that I, WILLIAM H. C. Hic- GINs, Jr., a citizen of the United States, re-

siding at Laporte, in the county of Laporte 5 and State of Ind1ana,'have invented a certain newoand useful Improvement in Valves, of which the following is a specication.

My invention relates `to improvements in carbureter valves and is .illustrated in the loyaccompanying drawing, which is a vertical *cross-section through a valve-adapted to be used to introduce fuel or .water into the mixing or carbureting chamber.

n win be 'understood .that lait liquid chamber is embraced between the upper wall A and the lower wall A1 and that the carbureting or mixing chamber lies below.

'the wallA1. The valve consists of the 'cylinder B screw-'threaded at B1, perforated at B2 and adapted to rest at .B3 on the .lower wall A1. It is surrounded by the 'gauze cylinder B4; Within the cylinder B is the cylinder C screw-'threaded at; C1, perorated above at C2, provided with a long hanging nozzle portion C3' which carries a washer` C* whereby altight. joint is made betweenthe upper part of the nozzle. C3 and the lower part of the wall A1.- The cylinder Bv is alsointernally screw-threaded at CA to engage the stem D, screw-threaded at' D1 and providedI with the hand wheel D2. The spring D3 is placed between the 'wheel D? andthe upper wall A. On the lowerend of the stem is the valve D4 with thehguide'iiange Dsipartlyencircling the 'stem above the valve and a valve seat D `in opposition to the valve.

The Ainner cylinder. is held-in position on the outer cylinder because of their screw- 40 t-lgreaded engagement and both are rigidly and firmly clamped to the lower wall A1 sc as to make a tight joint therewith on the lower side. The valve stem is screwed into the inner cylinder and the valve canbe set at any desired position by operating. the

`h/andA wheel' in opposition to the spiral spring..

y i The `fluid be it water or liquid fuel contained in the chamber between the walls A and A1 is first strained. through the gauze cylinder. It then enters the perforations B2, passes upwardly through the two cylinders, passes through the perforations C2 in the inner cylinder and down about the stemand out between the valve and valve zle. In practice the level of iuid inthe chamber isf maintained at about theheighto the perforation C2, and as long as a vacu-l um is created in the mixing chamber'belowl the wall A1 the fluid is raised to the level of the aperture C2, whereupon it iiows downwardly and out through the nozzle.'

l. A fuelsupply valve, for carbureters comprising a cylinder having a wall peri forate near its upper end, a valve and valve seat near its lower end and a jacket surrounding it, aV chamber formed within the jacket and surrounding the cylinder, said jacket having a Wall perforate toward its lower end.

2. Afuel supply Ivalve for carbureters comprising ajcylinderhaving'a wall Vper'- forate, nea-r its upper end, a valve and valve seatnear itslower end and `a jacket-surl Patenten Apnea, 1913..

seat through or along the walls of the nozrounding it, achamber formed within 'the. y

jacket and surrounding'the cylinder, said jacket having a wall erforate toward Athe lower end, said cylin er having a downwardly opening .conical discharge nozzle.

3. A fuel supply valve for carbureters comprising a cylinder having a wall per# forate near its upper end,-a valve and valve comprising a cylinder having a wall perforat'e near its upper'end, a vaive and valve seat near its lower end and a jack'et sur.l rounding it, a chamberE formed within the jacket and surrounding the cylinder, said jacket having a wall perforate toward the lower end.7 said cylinder having a'downwardly opening conical discharge nozzle, the valve seat in said :cylinder being located at the apexf the nozzle, said val-ve being carried by a valve stem screw threaded in the top of thccylinder.

5. A fuel supply valve for carburetcrs comprising a cylinder having a wall perforate near its upper end, a conical discharge nozzle at its lower vnd,a valve seat at the apex of the nozzle, a valve stem screw threaded in itsy upper end, and a needle valve carried by the valve stem and in opposition to the .valve seat,- a 'cylindrical jake.surroundii1g the cylinderhaving a vvall perforate at the bottom, a space between the cylinder and the: jacket and a screen surrounding'the perforated part of the jacket Wall. Y

6. A' fuel supply valve for carbureters comprising a cylinder having,r a Wall `vperforate near itsi upper en d, a 'conical discharge nozzle at its lower end, a valve seat atthe` apex o. the nozzle, a valve stem screw .threaded in the upper end of the cylinder, and a needle valve carried by the valve stem andiin opposition to the valve Seat, a cylindrical jacket surrounding the cylinder having a wall perforate at the bot.- tom, a space between the e 1linder andthe jacket, the cylinder containing a chamber incommunication at its upper end-With the space between the cylinder and the jacket. A 7. .A needle valvefor earbl'lreters' conlprising an outer perfor-ate sleeve, a screen Asurrounding.,r t-he base of lsaid sleeve and in opposition to the perforations therethrough, an inner perforate 'sleeve screw threaded in said outer. sleeve and terminat ing at'its bottom. in a bell mouthed discharge nozzle.` Y

8. A needle -valve for carbureters' comrisinfr an outer )e1-forato sleeve a screenl h 7 located adjacent its top, an annular conieal valve seat within said sleeve anda needle valve 1n "opposition to said seat.

V 9. A needle valve for carbureters com-z prisme,` an outer perforate sleeve, a screen surrounding the base of said sleeve and in opposition to theperforations therethrough,

an inner perforate sleeve screw threaded in said outer4 sleeve and teriniim'ing,l at its bottom in a bell-nouthed discharge nozzle, the pertorations in4 said inner sleeve being located adjacent its top,`an annular eoniealvalve' .seat Within said'sleeve and a needle valve 'in opposition to said seat, a

guide collar upon said needle. valve engagin" the walls ofsaid `sleeve and slots through said collar. ln testimony whereof, I alii my' signa- Hire in the uresence of two witnessesl this "28th day of October 1912. Y' lVlLL'lAM II. C. HIGGINS, Jn.
